变频器电量参数的工程测量

On the Engineering Measurement of Electrical Parameters of Converter

由于普通仪表是按直流量或工频率正弦量的测量而设计的,而变频器中的电压和电流波形的谐波成分较大,采用普通仪表对其进行测量时,具有一定的特殊性。通过对普通仪表的分析,正确地选择普通仪表,对变频器的电量进行测量能满足实际工程测量的需要。

As the ordinary instrument is designed according to the direct current or the sine quantities of power frequency, and the voltage and current waves in the converter have big harmonic component, measuring them with the ordinary instrument has its own characteristics.Making analysis on ordinary instruments and choos- ing the correct instrument to measure the electricity of the converter can meet the demand of engineering measurement.
